• Make sure that Java, JavaScript, or ActiveX is enabled in your browser. If you are using Internet Explorer,
click the Refresh button to be sure that the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure that you are using the correct login information. The user name is admin, and the default
password is password. Make sure that Caps Lock is off when you enter this information.
• If you are attempting to set up your router behind an existing router in your network, use the router in
WiFi bridge mode (see Use the Router in WiFi Bridge Mode on page 151) or set up the router as a WiFi
access point (see Use the Router as a WiFi Access Point on page 150).
• If you are attempting to set up your router as a replacement for an ADSL gateway in your network, the
router cannot perform many gateway services. For example, the router cannot convert DSL or cable
data into Ethernet networking information. NETGEAR does not support such a configuration.
You Cannot Access the Internet
If you can access your router but not the Internet, check to see if the router can obtain an IP address from
your Internet service provider (ISP).
Check the WAN IP Address
Unless your ISP provides a fixed IP address, your router requests an IP address from the ISP.You can
determine whether the request was successful using the ADVANCED Home page.
To check the WAN IP address:
1. Launch a web browser from a computer or mobile device that is connected to the network.
2. Select an external site such as netgear.com.
3. Enter http://www.routerlogin.net.
A login window opens.
4. Enter the router user name and password.
The user name is admin. The default password is password.The user name and password are
case-sensitive.
The BASIC Home page displays.
5. Click the ADVANCED tab.
The ADVANCED Home page displays.
6. Check to see that an IP address is shown for the Internet port.
If 0.0.0.0 is shown, your router did not obtain an IP address from your ISP.
If your router cannot obtain an IP address from the ISP, you might need to force your modem to recognize
your new router by restarting your network. For more information, see Sequence to Restart Your Network
on page 202.
